摘要：

Asymmetric synthesis of beta-lactams by the [2+2] cycloaddition of ketenes with chiral imines derived from D-(+)-glucose was carried out; predominantly cis-beta-lactams were formed with very high diastereoselectivity. The stereochemistry at C-3 and C-4 was established as 3S and 4R from the known absolute configuration of the sugar moiety. (C) 2003 Elsevier Science Ltd. All rights reserved.
